HINGE.

SPECIFICATION forming part of Letters Patent N0. 486,952,'dated November29, 1892.

Application filed March 16, 1892.

.To all whom it may concern.-

Be it known that I, WILLIAM SIssoN GIL- LESPIE, a citizen of the UnitedStates, and a resident of Bath Beach, in the county of Kings and Stateof New York, have invented certain new and useful Improvements inHinges, of which the following is a specification, ref? erence being hadto the accompanying drawings, in which- Figure lis asectional View ofmyimproved hinge, showing the same closed. Fig. 2 is a sectional Viewshowing hinge open, and Fig. 3 is a plan View showing hinge detached andclosed.

Like letters of reference indicate like parts in each.

My invent-ion relates to an improvement in a hinge of a kind for whichLetters Patent of the United States No. 470,043 were granted to me onthe 1st day of March, 1892; and it consists in providing another andmore positive means 0f securing a uniformity of action between themembers of one or more hinges on the same door or lid; in providingameans for keeping the crack of a door always closed against observation,no matter what the position of the door, and at the same time making adust or practically air tight joint when the door is closed, and,further, in providing metallic stops for the different members of ahinge rather than leave this office to be performed by the hingedsubstance, as shown in my former patent, relation in general being tohinges incased entirely within the door and jamb and invisible when thedoor is closed. These ends I accomplish in the two former provisions bythe employment of two ordinary [iat pin-aps B and C, with anintermediate member connecting them by means of fixed pins, saidintermediate member A being formed like a rectangular letter U, with itsupper ends terminating in ordinary cylindrical hinge-knuckles and havingsecured to its bottom part on the inside a piece or strip F of the samerigid material of which the door and jamb are composed and so formed bybeing hollowed out at the sides as to play or slide on contra-curvedsurfaces formed on the edges of the door D and jamb E, these curvesSerial Nc. 425,133.

beingconcentricwiththepinsof saidknuckles, 5o thus maintaining apracticalcontact between the piece F and the edges of door and jamb Dand E during the entire convolution of the hinge or parts thereof. Areference to the drawings will show how this piece F, secured to themember A of each hinge and working on the curved edges of the door D andjamb E, will always close the crack, connect the hinges one withanother, and thus secure uniformity of operation between their sev- 6oeral parts and at the same time form a covered joint when the door orlid is closed, the piece F being so constructed as to never entirelyleave the support of nor fail to support the member A or the edges ofthe door D or jamb E. t

In my former patent the thin lips of thedoor D and jamb E, now shown inconnection with the piece F, Figs. 1 and 2, either one striking againstthe inside of members A, determine 7o the commencement of operation inthe opposite knuckle of the-hinge, and whereas africtional resistancegreater than the strength of these lips, owing to the weight of a dooror other cause, Inight damage the hinged parts I have provided a stop inthe hinge itself, which in the present illustration will only permit aquarter-turn of the iiaps Band C on the intermediate member A. This stopI form by makingablank ward with one-quar- 8o ter removed in the centerof each knuckle. The remaining parts of said wards in iiaps B and Cstriking against the remaining part of the wards in member A will form ametallic stop sufficient to avoid any friction in either of the pins orknuckles and prevent any injury to the lips of door D or jamb E. (Seeknuckles between intermediate member A and B and member A and Hap O inFigs. 1, 2, and 3.). Of course it is understood that all of 9o the abovemay refer to a single hinge as well as to two or more where only one maybe used or is necessary.

Having now described the improvement on my hinge, its construction andoperation,`what I claim as new, and desire to secure by United StatesLetters Patent, is-mh In a concealed hinge, the combination of 'nwoordinary flat pin-aps, with a rectangu- Signed at Brooklyn,n the countyof Kings lar U- shaped intermediate member oonneetand State of New York,this 10th day of March, ro ing said flaps, and a strip secured to thein- A.
